Pinout
The LMV339IRUCR is a quad comparator integrated circuit. It typically comes in a 14-pin package. Each comparator within the chip can compare two voltages and output a digital signal based on the comparison. The main function of the LMV339 is to provide a means of comparing input voltages and providing logic-level outputs. The 14 pins generally include:
1. VCC (Positive Supply Voltage)
2. GND (Ground)
3. Four inverting inputs (one for each comparator)
4. Four non-inverting inputs (one for each comparator)
5. Four output pins (one for each comparator)
This configuration allows the LMV339 to perform four independent voltage comparisons. Note that the specific pin assignment can vary based on the package type, so it is always best to refer to the datasheet for precise details.
